Got brick questions? We've got the answers!

Chimney leaks can caused by a number of things. The
pictures below show examples of where chimney leaks can occur. The
first picture shows the chimney cap. The next two pictures depicts
a properly "flashed" chimney. Improper flashing can also
cause the leaking.

SOLUTION:

Always start at the top of the chimney. Check to see
if your chimney cap is properly installed or in good shape. If you
do not have a cap on your chimney, you may want to purchase one.

Check the mortar bed on top of the chimney for cracks. If large cracks
are prevalent, you may want to purchase a chimney cap that covers
the entire top of the chimney.

Check the brick and mortar, especially on the top 3 or 4 courses and
look for damage.

Take a water hose and wet the outside of the chimney. Note the amount
of water that appears to be absorbing into your brick and mortar.

Check the flashing at the base of the chimney and make sure water
can not get behind the flashing material.

If damage is found, repairs need to be made by repairing mortar or
replacing brick. After the chimney has been repaired, apply PROSOCO
Weather Seal Siloxane PD. If you should have a very porous brick,
PROSOCO Custom Masonry Sealer should be used.
